ABSTRACT
One of the most fascinating permanent questions in philosophy is what to think of their own experiences. Nowadays philosophers like to talk and write about 'response-dependent properties' to get a grip on what is going on when we meet reality in our experience. Affordance shows us the way in the complex and obscure jungle of response-dependent properties. Other people's words are affordances for me, and this discloses two divisive complications that lie silently and unnoticed under the surface of our language community. In this language community, two presuppositions secretly play the obscure leading role, presuppositions that can bind us and that can divide us. One can presuppose that scientists have normal language skills, and that cognitively they are in favourable circumstances. Adopt the investigative attitude when looking at their own presuppositions about normal language skills and favourable cognitive circumstances.
